Throughout the specification and claims, when a part includes a certain component, it means that it may include other components, not to exclude other components unless specifically stated otherwise.

1 is a view showing the operation sensitivity setting device for construction equipment according to the present invention.

As shown in FIG. 1, the apparatus is largely comprised of a manipulated variable detecting means 101, a control unit 102, an actuator 103, and an input unit 104.

That is, the manipulated variable detecting means 101 for detecting the manipulated variable of the operating lever and the manipulated variable detected from the manipulated variable detecting means 101 are input according to the relationship between the manipulated variable and the driven amount stored in advance (hereinafter referred to as 'operating sensitivity'). The control unit 102 that calculates the driving amount, the actuator 103 that operates according to the driving amount calculated by the control unit 102, and the manipulated variable-drive amount relationship stored in the control unit 102 in accordance with user key operation Alternatively, the structure includes an input unit 104 for changing.

In addition, the structure further includes a display unit 105 for displaying the relationship between the manipulated variable and the driven amount on the screen upon request according to a user key operation.

Here, the input unit 104 is connected to the control unit 102 to set or change the relationship between the manipulated variable-drive amount stored in the control unit 102 (that is, the operation sensitivity) according to the user key operation. The relationship of the driving amount according to the input manipulation amount is displayed by reflecting the change in the display unit according to the manipulation of the input unit 104, and the final set value is displayed by the storage unit (not shown) of the control unit 102 according to the command of the input unit 104. ) Then, when the relationship between the manipulated variable-drive amount is changed, the input unit 104 moves a specific point of the line where the manipulated variable formed on the display unit 105 meets the drive amount according to the user key operation, so that the user can change the amount of the manipulated variable-drive amount. The relationship is changed, and the manipulation amount-drive amount relationship is defined as a polynomial of 1 or more orders so that the user can change it. In addition, the maximum and minimum drive amounts and the manipulated amounts may be set to restrict the user from setting the relationship between the manipulated variable and the driven amount beyond a set input and output range. That is, by setting the maximum value and the minimum value of the input manipulated variable or output drive amount, it is possible to restrict the user to change the relationship of the manipulated variable-drive amount within the range.

The control unit 102 receives the operation amount of the operation lever from the operation amount detection means 101, calculates the driving amount by applying the input operation amount to the relationship between the operation amount and the driving amount previously stored ('operation sensitivity'). After the determination, the operation of the actuator 103 is controlled according to the determined driving amount. That is, the relationship between the driving amount of the actuator 103 according to the user's operation amount is stored and reproduced when the actuator 103 is driven. The manipulation amount-drive amount relationship is set or changed by the user through the input unit 104 and receives the corresponding information from the input unit 104 and is stored in a predetermined storage unit in the control unit 102.

Are stored in.

When the relationship between the manipulated variable and the drive amount is changed, the input unit 104 moves a specific point of the line where the manipulated amount formed on the display unit 105 meets the drive amount according to a user key operation, so that the user operates the manipulated variable-drive amount. To change the relationship.

The manipulation amount-drive amount relationship is defined as a polynomial of at least one order so that the user can change it.

In addition, the maximum and minimum drive amounts and the manipulated amounts may be set to restrict the user from setting the relationship between the manipulated variable and the driven amount beyond a set input and output range.

That is, by setting the maximum value and the minimum value of the input manipulated variable or output drive amount, it is possible to restrict the user to change the relationship of the manipulated variable-drive amount within the range.

As described above, the present invention is to configure the system so that the user can set the operation sensitivity according to the operation section of the proportional control operation device when controlling the drive device of the proportional control method using a proportional control input device in construction equipment In addition, the user can change the setting of the operation sensitivity according to the attachment or the working conditions to be mounted on the drive device, thereby improving the operation performance and the driver's convenience.
